ABSTRACT

The invention relates to a composition comprising, in a physiologically acceptable medium, a volatile silicone fatty phase comprising at least one non-cyclic volatile silicone oil, wherein the volatile silicone fatty phase has an evaporation profile such that the mass of the at least one volatile silicone oil evaporated after 30 minutes is from 2 mg/cm 2  to 9 mg/cm 2 . The invention also relates to making up and caring for human keratin materials using the inventive compositions.

[0001] This application claims benefit of U.S. Provisional Application No. 60/461,400, filed Apr. 10, 2003.

[0002] Disclosed herein is a cosmetic composition comprising at least one volatile silicone oil. Further disclosed herein is a non-therapeutic care or make-up process for human keratin materials, comprising applying the composition to the keratin materials.

[0003] Volatile silicone oils are commonly used in cosmetic compositions for their good cosmetic properties, such as their pleasant feel on contact with the skin. These oils may also evaporate quickly after they have been applied to keratin materials. However, if their rate of evaporation is too high, the user may not have sufficient time to apply the cosmetic product to the keratin materials, or sufficient time to apply the cosmetic product to the keratin materials uniformly.

[0004] The volatile silicone oils most commonly used in cosmetic products are cyclic silicones containing from 4 to 6 siloxane groups (generally known as D4, D5 and D6) and containing only methyl groups.

[0005] Disclosed herein is an alternative for formulating compositions comprising volatile oils, such as volatile oils that are compatible with the ingredients usually used in cosmetic compositions.

[0006] The inventor has discovered that such a composition may be obtained by using at least one particular volatile silicone oil that may give the volatile fatty phase a particular evaporation profile.

[0007] Disclosed herein is a composition comprising, in a physiologically acceptable medium, a volatile silicone fatty phase comprising at least one non-cyclic volatile silicone oil, wherein the volatilesilicone fatty phase has an evaporation profile such that the mass of the at least one non-cyclic volatile silicone oil evaporated after 30 minutes ranges from 2 mg/cm² to 9 mg/cm².

[0008] Further disclosed herein is a composition comprising, in a physiologically acceptable medium, a volatile fatty phase comprising at least one non-cyclic volatile oil with a surface tension of less than 21 mN/m, such as less than 20 mN/m, wherein the volatile fatty phase has an evaporation profile such that the mass of the at least one non-cyclic volatile oil evaporated after 30 minutes ranges from 2 mg/cm² to 9 mg/cm².

[0009] Even further disclosed herein is a cosmetic make-up process or non-therapeutic treatment process for a keratin material, comprising applying to the keratin material a composition as defined above.

[0010] The term “volatile oil” means an oil (or a non-aqueous medium) that may evaporate on contact with the skin in less than one hour at room temperature and atmospheric pressure. The volatile oil may be a volatile cosmetic oil, which is liquid at room temperature, which may, for example, have a non-zero vapour pressure, at room temperature and atmospheric pressure, or may have a vapour pressure ranging, for example, from 0.13 Pa to 40 000 Pa (10⁻³to 300 mmHg), further, for example, from 1.3 Pa to 13 000 Pa (0.01 to 100 mmHg), such as from 1.3 Pa to 1300 Pa (0.01 to 10 mmHg).

[0011] The composition disclosed herein comprises a physiologically acceptable medium, such as a cosmetically or dermatologically acceptable medium, i.e., a medium that is compatible with keratin materials such as the skin, mucous membranes, the hair, the eyelashes, the eyebrows and the nails.

[0012] The composition disclosed herein comprises a volatile silicone fatty phase comprising at least one non-cyclic volatile silicone oil, wherein the volatile silicone fatty phase has an evaporation profile such that the mass of the at least one non-cyclic volatile silicone oil evaporated after 30 minutes ranges from 2 mg/cm² to 9 mg/cm², such as from 2 mg/cm² to 8 mg/cm2, from 2 mg/cm² to 7 mg/cm², from 2.3 mg/cm² to 6 mg/cm², from 3 mg/cm² to 5.5 mg/cm², or from 3 mg/cm² to 4.7 mg/cm².

[0013] The evaporation rate of the oil is measured according to the protocol described below.

[0014] Moreover, in one embodiment, the composition comprises a volatile fatty phase comprising at least one non-cyclic volatile oil with a surface tension of less than 21 mN/m, such as less than 20 mN/m, wherein the volatile fatty phase has an evaporation profile such that the mass of the at least one non-cyclic volatile oil evaporated after 30 minutes ranges from 2 mg/cm² to 9 mg/cm², such as from 2 mg/cm² to 8 mg/cm², from 2 mg/cm² to 7 mg/cm², from 2.3 mg/cm² to 6 mg/cm², from 3 mg/cm² to 5.5 mg/cm², or from 3 mg/cm² to 4.7 mg/cm².

[0015] Such a non-cyclic volatile oil is chosen, for example, from non-cyclic volatile silicone oils.

[0016] The surface tension of a volatile oil is measured according to the protocol described below.

[0017] The non-cyclic volatile silicone oil may be chosen from linear and branched volatile silicone oils.

[0018] The non-cyclic volatile silicone oil may be chosen, for example, from:

[0019] the non-cyclic linear silicones of formula (I):

(R)₃SiO—((R)₂SiO)_(n)—Si(R)₃   (I)

[0020] in which R, which may be identical or different, is chosen from:

[0021] saturated and unsaturated hydrocarbon-based radicals comprising from 1 to 10 carbon atoms, such as from 1 to 6 carbon atoms, optionally substituted with at least one substituent chosen from a fluorine atom and a hydroxyl group, and

[0022] a hydroxyl group,

[0023] wherein one of the radicals R may be a phenyl group, and

[0024] n is an integer ranging from 0 to 8, such as from 2 to 6 and further such as from 3 to 5, and

[0025] wherein the silicone compound of formula (I) comprises not more than 18 carbon atoms, such as not more than 17 carbon atoms, not more than 16 carbon atoms, or not more than 15 carbon atoms;

[0026] the branched silicones of formulae (II) and (III) below:

(R)₃SiO—[((R)₃SiO)RSiO]—((R)₂SiO)_(x)—Si(R)₃   (II)

(R)₃SiO]₄Si   (III)

[0027] in which R, which may be identical or different, is chosen from:

[0028] saturated and unsaturated hydrocarbon-based radicals comprising from 1 to 10 carbon atoms, optionally substituted with at least one substituent chosen from a fluorine atom and a hydroxyl group, and

[0029] a hydroxyl group,

[0030] wherein one of the radicals R may be a phenyl group, and

[0031] x is an integer ranging from 0 to 8, and

[0032] wherein the silicone compound of formula (II) or (III) comprises not more than 18 carbon atoms, such as not more than 17 carbon atoms, not more than 16 carbon atoms, or not more than 15 carbon atoms.

[0033] For the silicones of formulae (I), (II) and (III), the ratio of the number of carbon atoms to the number of silicone atoms may range from 2.25:1 to 4.33:1.

[0034] The silicones of formulae (I) to (III) may be prepared according to the known processes for synthesizing silicone compounds.

[0035] When the volatile silicone by itself has the evaporation profile as defined above for the volatile fatty phase, it may be present as sole volatile silicone oil in the composition, and may, for example, constitute the entire volatile phase of the composition.

[0036] When the volatile silicone does not by itself have the evaporation profile as defined above for the volatile fatty phase, it is then used as a mixture with another volatile silicone that has an evaporation profile in accordance with that described above, such that the mixture of volatile silicones has said evaporation profile.

[0037] Examples of non-cyclic volatile silicones that may be used are given below; these silicones may be used alone or as a mixture so as to obtain the evaporation profile defined above.

[0211] Measurement of the Rate of Evaporation of an Oil:

[0212] 15 g of oil or of the mixture of oils to be tested are placed in a crystallizing dish (diameter: 7 cm) placed on a balance that is inside a chamber of about 0.3 m³ with a regulated temperature (25° C.) and a regulated hygrometry (50% relative humidity). The liquid is allowed to evaporate freely, without stirring, while providing ventilation with a fan (Papst-Motoren, reference 8550 N, rotating at 2700 rpm) positioned vertically above the crystallizing dish containing the solvent, the vanes facing the crystallizing dish and being 20 cm from the bottom of the crystallizing dish. The mass of oil remaining in the crystallizing dish is measured at regular intervals. The evaporation rates are expressed in mg of oil evaporated per unit of surface area (cm²) and per unit of time (minutes).

[0213] Measurement of the Surface Tension of a Volatile Oil:

[0214] The surface tension is determined by the “hanging drop” method. It is measured at 25±1° C. using a Fibro DAT 1100 tensiometer, sold by the company Fibro (Sweden). A drop of volatile oil is formed using a syringe controlled by the tensiometer at the outlet of a Teflon cannula with an inside diameter of 200 μm and an outside diameter of 1.5 mm, held in a vertical position. The volume of the drop is from 1 to 10 microlitres such as from 5 to 10 microlitres. The hanging drop is observed using a camera integrated into the measuring device, and its shape is parametized by the software of the Fibro DAT 1100 tensiometer using a resolution method of the Laplace equation. The result is given in mN/m.
